What causes the left front door window of Nissan Sylphy to fail to roll up or down?

[MiaLynn]

The reasons why the left front door window of Nissan Sylphy cannot roll up or down are as follows: 1. Damaged window lift motor or poor contact of the electronic control wiring harness: If there is a burnt smell or abnormal noise in the door panel when the window button is pressed for a long time, it is likely that the window lift motor components are damaged. In this case, it is recommended to directly contact a 4S shop or auto repair shop to replace the window lift motor. 2. Motor overheating protection: To protect the power supply circuit, window lift motors generally have an overheating protection mechanism. If the components overheat for some reason, the motor will enter an overheating protection state, causing the window to fail to roll up or down. In this case, simply wait for the motor to cool down. 3. Excessive resistance in the glass guide channel: The door glass guide channel is a detail that is easily overlooked. During use, dust accumulates in the glass guide channel, increasing resistance, which may make it difficult for the glass to roll up over time. Regularly clean debris from the window glass guide rail or use grease for lubrication.
